CSS-遍历单词

我有以下简单的布局，该布局使用CSS在短语之间循环。

.switch-text {
  position: relative;
}

.switch-text em {
  opacity: 0;
  font-style: normal;
  white-space: nowrap;
  position: absolute;
  left: 5px;
  animation-name: example;
  animation-duration: 3s;
  animation-iteration-count: infinite;
}

.switch-text em:nth-child(2) {
  animation-delay: 1s;
}

.switch-text em:nth-child(3) {
  animation-delay: 2s;
  opacity: 1;
}

@keyframes example {
  0% {
    opacity: 0;
  }
  33% {
    opacity: 0;
  }
  66% {
    opacity: 0;
  }
  100% {
    opacity: 1;
  }
}
<span class="switch-text">
	<em>environment 1</em>
	<em>environment 2</em>
	<em>environment 3</em>
</span>

<br>
<br>
<hr>
<br>
<br>

<span class="switch-text">
	<em>environment 1</em>
	<em>environment 2</em>
	<em>environment 3</em>
    <em>environment 4</em>
	<em>environment 5</em>
	<em>environment 6</em>
</span>

我的最高版本正常工作，但当我添加多个项目时，最低版本是元素重叠。

有人知道为什么吗？

在将动画设置到第三级之前，您必须从第二个列表中删除3个列表。如果需要更多，则必须相应地添加动画。
